The darkcurrent calibration is a technical calibration. It is not used to calibrate other calibrations or science data. The darkcurrent template acquires a sequence of dark frames with different DITs. The pipeline recipe fits the relation darkcurrent( DIT ). While the dark level retrieved from the dark recipe gives the dark counts in ADU for a master dark of a given DIT, the darkcurrent gives the current in ADU/sec in a more accurate manner.

Each detector has its own dark current. There following map shows the values in ADU/sec (June 2010):

red labels mark detectors with relatively high dark current, green labels mark detectors with relatively low dark current.
